0.6 + –1 331 = 1.69 – 6 25
= 0.36 + (–11) = –4.31 = 144 – 0.5
= 0.36 – 11 25 1
= –10.64 = –

(–4) – 81
= – 64 – 9 = –39 = 8.992
= –73

Contoh 5. 1.44 + (–1.5) ÷ –0.027 1 2 1

64 + (–0.3) ÷ –0.008 = 1.2 + 2.25 ÷ (– 0.3) 4
= 1.2 + (–7.5) 1 1
= 8 + 0.09 ÷ (– 0.2) = 1.2 – 7.5 = 7 – 16 ÷ 2
= 8 + (– 0.45) = – 6.3 1
= 8 – 0.45 = 7 – 16 × 2
= 7.55 1
= 7 –
